Structural equation model for the association between latent Metals exposure (left circle) informed by concentrations of W-As, W-Mn, and B-Pb at pregnancy, toddlerhood, and childhood (left rectangles) to latent Antibody concentration (right circle) informed by age-5 diphtheria and tetanus antibody (right rectangles). Note: Covariates (middle rectangle) include maternal education, child sex, and breastfeeding duration. Single headed arrows represent regressions between variables (factor loadings when observed variable is regressed on its latent construct). The double-headed dashed arrows represent specified correlations between residuals of observed variables
